I have what is probably a simple problem. I have a data file from an MCMC
Bayes estimation problem that is a vector of 500,000 numeric values (just
one variable) ranging from 100,000 to 700,000. I need to display the
histogram of this data in a high quality graphic for a figure in a journal
publication. I want 100 bins so as to display a reasonable complete and
smooth histogram, and I need the Y-axis to display the bin proportions.

I'm new to all of the graphics capabilities of R.

Can anyone provide me with the command I need to issue to the call to hist
to get the output that I desire?

 I assume that once I have the desired histogram I will be able to save it
in a format like .eps that will permit it to be reproduced in high
resolution. But any suggestions for this task would also be appreciated.

Regards,

Nick
